I've seen CA applied to a very tight crack and near instantly run several inches in either direction along the crack, showing the crack to extend past where it was previously visible. I've never seen that kind of capillary action happen with epoxy. West system is what I use. YMMV. Joe's trick of using the heat is sure to improve epoxy's flow performance. But heat will also speed the cure time for epoxy. I would think a moderate amount of CA that mostly soaks into the wood would not hinder the performance of epoxy.

West system will penetrate into pretty much any crack you'll find. I say "pretty much" because if I said "any", with absolute certainty someone would come up with some pathological situation bearing no resemblance to the cracked pin block discussed as "proof" that it won't work in any situation at all.
